array
getEntityManagers()

Return Value

EntityManager
resetEntityManager(string $name = null)

This method is useful when an entity manager has been closed because of a rollbacked transaction AND when you think that it makes sense to get a new one to replace the closed one.

Be warned that you will get a brand new entity manager as the existing one is not useable anymore. This means that any other object with a dependency on this entity manager will hold an obsolete reference. You can inject the registry instead to avoid this problem.
